To a/Z LU/1,0111, /f/ 'nm/y concern:

Be it known that I, CHARLES F. N IoKnL, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented a certain new and useful Improvement in `Windingl\/Iachines, of which the following is a full, clear, concise, and exact description.

My invention relates to a machine for winding wire upon closed cores, the machine being particularly adapted for winding loading-coils for telephone-circuits. Such coils consist of a ring-shaped core of laminated iron having two wire helices wound upon semicircular segments thereof. It has been my object to construct an improved machine for winding closed cores in which the wire being wound will at all times be held under a constant and uniform tension and the formation of slack wire prevented.

My invention contemplates a winding-machine having a spool-ring and a winding-ring mounted close together, so as to rotate independent] y of each other, said rings being' adapted to be interlinked with a closed core anda guide being provided over which the wire to be wound is led from the spool-ring to the core. The guide is suitably mounted within the winding-ring, so as to be capable of movement about the circumference thereof, and is provided with a yielding connection with the winding-ring, whereby as the winding-ring is rotated the guide is allowed to move in its mounting sufliciently to maintain the wire being wound under a constant and uniform tension and take up any slack which may tend to form.

I will describe my invention particularly by reference to the accompanying drawings, and the parts, improvements, and combinations which I consider novel will be pointed out in the appended claims.

Figure lis a View in elevation of a machine for winding closed cores, with the spool-ring removed to show the means which I have devised for preventing` the formation of slack wire. Fig. 2 is a plan view of the machine.

Fig. 3 is a perspective view of the machine, taken from the side opposite to that shown in Fig. l; and Fig. li is adiagrammatic view illustrating the operation of my improved device in preventing the formation of slack wire.

The same letters of reference are used to designate the same parts wherever they are shown.

The principal operating parts of the machine are the spool-ring' c and the windingringI l), which are mounted side by side, so as to rotate independently of each other, both of said rings being provided with removable seg'- ments, so that a closed core may be interlinked therewith, the winding-ring carrying a winding sheave or pulley b' substantially in the central plane between the two rings. The wire to be wound upon the core is led from the spool-ring c, upon which it is iirst wound in the usual way o-ver the bridge-piece ci', around the winding-sheave 2)', carried by the winding-ring b, and thence to the core. The winding-ring Z2 may be rotated by a suitablydriven shaft b, which may operate a pinion meshing with internal gear of the windingring. 'Ihe winding-ring is adapted to carry the winding-sheave around and through the core, and in its rotation the wire is pulled oiif thc spool and wrapped around the core, the spool being arranged to be frictionally rotated by the pull of the wire as it is wound to feed the same.

The core to be wound is held horizontally in a standard c by clamps c2 c2, the standard being pivotcd to the bed-plate of the machine in such a way that the core may be rotated about a vertical axis coinciding with the axis of the core while the machine is in operation to guide the wire which is being applied to said core through a semicircumference. The standard may be rotated by means of a geartrain actuated by a ratchet-pawl (Z, carried upon an oscillating hand-lever c. When one half of the core has been wound, it may be taken out of the holding-clamps c2 c2 and turned around, whereupon the other half may be wound in the same manner.

During the operatingof the machine it will be noted that the wire is pulled oil' the spoolring a, while the sheave or pulley Z/ is moving away from the coil at a rate much faster than during the other half of the revolution, while the guiding-sheave is moving toward the coil. This would tend toward the formation of slack wire, due to the fact that more wire is pulled oii the spool than is called for by the semicircumference of the coil, and in IOO order to avoid this diiiiculty the windingsheave is journaled upon a support f, slidably mounted in the side of the winding-ring the winding-sheave thus lying approximately in the central plane between the two rings e The support f is provided with a yielding connection with the winding-ring, which may be a spring 4f/,as illustrated. Said spring is attached to the support f and passes partially7 around the circumference of the winding-ring being anchored to said rino', the spring preferably lying in a slot formed in the side of the winding-ring wWhen the machine is in operation and the winding-ring rotating in the direction of the arrow, Figs. l and et, as the winding-sheave moves away from thc core being wound the spring' extends or elongates and allows the support f to move back, due tothe pull of the wire being wound, far enough so that too great a strain will not be placed upon the wire, but so that the same will be under sufhcient tension to maintain the wire tant. As the guide-sheave moves around and is approaching the core, the spring g contracts and pulls the sheave rapidly toward the core, thus tak- `ing up the slack which is tending to form and at the same time maintaining the tension upon the wire uniform. lith a machine of this construction very fine wire may be wound without danger of breaking, as the wire will not be subjected to sudden and severe strains, but will be kept under an even and uniform tension while being wound.

In order to prevent the spool-ring from rotating any faster than is required by the amount of wire to be pulled off by the movement of the guide-sheave through a given arc, a braking mechanism or drag /L is applied thereto. Said drag /t may comprise a brakearm L', normally maintained by a spring h2 in position to effect the engagement of a brake-shoe carried thereby'with the inner surface of the spool-ring. Ihe power of said brake may be regulated by a lever 7a3 and thumb-screw 7b4, controllingI the pull of said spring upon the brake-arm. Said arm is also secured to one end of a pivoted lever the other end whereof is adapted to be engaged by a cam-roller /z/ to remove the brake-shoe from Contact with the spool-ring when desired.
